As for the fastest accelerating production car, it's the Ultima GTR720. 0-100mph in 5.3 seconds.... Ask if his Mini would beat that
Unfortunately the Ultima doesnt count as a production car. There is a big debate about it, its something to do with the fact you can put any engine you want in it basically. This is why its not the fastest production car around the ring (even though it was RAPID).
My guess would be the Corevette Z06, the 2006 version is mid 11's, not sure what the newer one is. I'll ask my mate as he's a yank buff.
JAmes.
